12. A receiver for receiving an incident signal, said incident signal including information herein, said receiver comprising:
-
a phased array antenna, said phased array antenna comprising an antenna array of a plurality of spatially separated antenna elements, each of said antenna elements producing an associated electrical signal in response to said incident signal, a phase shifter applying a phase shift to each said associated electrical signal and producing a corresponding phase shifted electrical signal, a phased array controller, said phased array controller controlling the phase shift applied by said phase shifters to said electrical signals, and a combiner for combining said phase shifted electrical signals thereby producing an electrical output signal, wherein said applied phase shifts result in the information contained in said incident signal being output.

16. A receiver for receiving at least two incident signals, said incident signals including information therein, said receiver comprising:
-
a phased array antenna, said phased array antenna comprising an antenna array of a plurality of spatially separated antenna elements, each of said antenna elements producing associated electrical signals in response to said incident signals, at least two phase shifters, each phase shifter applying a phase shift to each said associated electrical signals and producing corresponding phase shifted electrical signals, a phased array controller, said phased array controller controlling the phase shift applied by said phase shifters to said electrical signals applied by said additional phase shifter; and
a combiner for combining said phase shifted electrical signals thereby producing at least two electrical output signals, wherein said applied phase shifts result in the information contained in said at least two incident signals being output.
